BUCKET FOR DEEiF-XVELL PUMPS.

Application filed November 25, 1919. Serial No. 340,936.

To all whom it 17mg, concern:

Be it known that I, AROHILLES A. BARTON, a citizen of the United States, residing at Glendale, in the county of Los Angeles and State of California, have invented a new and useful Improvement Comprising a Bucket for DeepWVell Pumps, of which the following is a specification.

lvlly invention relates to pumps, and more particularly to pumps which are used for pumping irrigation or domestic water, these pumps oiten'operating todepths of several hundred feet and being of large capacity.

It 'is standard practice in the art to provide a pump head which is located over the well at the surfaceofth'e ground and to-provide buckets, which are operated through pump rods, being reciprocated in a pump barrel which is submerged in the water of 20' the well.

It is standard practice in the art, at the present time, to provide such buckets with a central opening, the top of which is closedby a suitable clapper. These clappers are r provided with an outer and inner seat. The general type of clapper is that disclosed in the patent to Fulton, No. 1,164,178, patented December 14, 1915. Pumps equipped with buckets of this type soon become ineiiicient under severe service due to the fact that the inner seat of the clapper is rapidly cut or worn away.

An object of my invention is to provide a clapper which has a single seat, the inner seat being dispensed with entirely. As the clapper seats only on the outer seat, which is of large area as compared with the inner seat, it is not difficult to manufacture valves which are initially tight and which will stay tight over long periods. These clappers are ordinarily free to slide up and down on a stem by which the bucket is supported.

It is a further object of my invention to provide means for making a water tight closure between the clapper and the stem, this closure being suliiciently flexibletoallow the clapper to make a perfect contact on the outerseat even where this seat is initially not perfectly concentric with the stem, or where it becomes slightly eccentric due to erosion or wear- A still further object of the invention is to provide a novel form of bucket construction in which a skeleton type of bucket is used,

below, a portionthereof being shown in sec-- tion on a of Fig. 1. v l In the embodiment of the invention shown in these figures, 11 is a stem which has a plane represented by the line 3- central cavity 12 and which has a coupling,

14 formed on its upper end. This coupling 14 1s threadedas shown at 15 for the receptlon of the string of pump rods which in the case of this particular bucket would be tubular. The opening 12 is provided for the passage of rods or tubes to lower buckets, it being common practice to build dee well pumps either duplex or triplex. Threaded as shown at on the stem 11 is the hub 21 of a skeleton bucket 22; this bucket consists of a series ofsix ribs 28 which are connected at their lower end by a base ring 24 and which are connected at their upper end by a seat ring 25. Formed in the seat ring 25 is a valve seat26 in which a clapper 27 may be seated. The clapper 27 is provided with a central cavity surrounding the stem 11 in which is located a pair of cup washers 30 which are separated by a spacer 31. The cup washers. are locked in place by means of a clamping ring 32 which is threaded into the clapper 27. A retaining nut 34 is also threaded on the clamping ring 82 serving as a jam nut to retain the clamping ring in place, and also serving as a guide for a pressure spring 35 which. is seated thereon and also 011 a flange 36 formed on the coupling 14. Seated in. a cavity formed near the lower end of the stem 11 is a split collar 40 which is made in two halves separated by a. slot 41. The split collar 40 is retained in place by a lip 42 formed on the hub 21. The peripheries of the ribs 23 are machined to receive a series of clamping rings 50. The clamping rings are each provided with an inner lip 51 fitting into an annular cavity 52.

The seat ring 325 and each of the clamping rings being provided with one of these cavities 52. The seat ring 25 and each of the clamping rings 50 is also provided with an upper flange 53 on its lower edge, each of the rings 50 having a lower flange 5% on its up per edge. Each of the clamping rings 50 is also provided with a lip 55 which fits into the cavity 52 of the next higher member cup leathers 56 fitting over these inner lips and being solidly clamped between the flanges 53 and 54-. For the purpose of exercising the necessary pressure a clamping ring (30 is pro- \'l(l(3(l on the bottom of the bucket, this clamping ring being secured in place by means of "i" head bolts 61. The clamping ring (it) is provided with a lip 62 corresponding in shape to the lip 51. on the members 50.

The method of securing the head 21 on the stem 11 is as follows The members are threaded together with the hub 21 in a somewhat higher position on the member 11 than is shown in the draw ings. The split collar 40 can then be readily put in place and the hub 21 can be turned to force the lip -it2 downwardly over the split collar 40 until the lower end of the hub 21 rests solidly thereon. A set screw is then forced into place preventing the head 21 from turning on the/stem 11.

The method of Operation in the above is as follows ()n the down stroke of the bucketthe pressure of the water lifts theclapper 27 from its seat against the action of the spring 35, this clapper remaining off its seat until the bucket starts to move upwardly when the spring 35 forces the clapper downwardly against the seat26.

It will be noted that the cup leathers 80 provide a tight closure between the clapper 27 and the stem 11 and that this closure is flexible thus allowing the clapper to be inclined slightly to suit any eccentricity of the seat 26 with relation to the stem 11.

It will further be noted that the bucket is in a skeleton form, the water closure being provided by means of the clamping rings 50. It will further be noted that the bolts 61 are set very close to the line of pull on the ring 60 so that distortion of this ring is practically impossible.

The invention disclosed herein is an improvement on that shown in my copending application Serial No. 255,385, filed Sept. 23, 1918.

I claim as my invention l. A bucket structure comprising a continuous seat ring; a series of ribs projecting downwardly therefrom; a series of clan'iping rings fitting over said ribs; a series of cup leathers clamped in place between said clamping rings; a lip formed on each ring over which said cup leathers lit, each of said lips fitting into a cavity in an adjacent ring; and means forcing said clamping rings towards said seat rings.

2. A bucket structure comprising a continuons seat ring; a series of ribs projecting downwardly therefrom; a series of clamping rings fitting over said ribs; a series of cup leathers clamped in place between said clamping rings; a lip formed on each ring over which said cup leathers fit each of said lips fitting into a cavity in an adjacent ring; a bottom clamping ring pressing on the last of said series of cup leathers; a series of bolts each engaging one of said ribs and projecting through said bottom clamping ring; and a nut on each bolt acting against said bottom clamping ring.

In a pump, the combination of: a structure; a series of rings slidably mounted on said structure, each ring having a lip fitting inside an adjacent ring; and cup leathers on said lips between said rings.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 18th day of November, 1919.
